What are five examples of buffer solutions?

Answer 1

You want only FIVE, why not 55?

Five examples of buffer solutions are as follows: a weak acid and its conjugate base in significant concentrations make up the solution.

#(i)# #"Acetic acid/sodium acetate"#

#(ii)# #"Ammonium chloride/ammonia"#

#(iii)# #"Bicarbonate/carbon dioxide (carbonic acid)"#

#(iv)# #"dihydrogen phosphate/biphosphate"#

#(v)# #"Citric acid/citrate"#
